Spots Global Cancer Trial Database for Evaluate the Neuroprotective Effect of Vitamin B6 and Vitamin B12 Against Vincristine Induced Neurotoxicity in Acute Lymphoblastic Leukaemia Patients

Study Description

Brief Summary: This study will be conducted to evaluate the effect of vitamin B6 and vitamin B12 in reducing the incidence and severity and delaying the onset of Vincristine Induced neurotoxicity in Acute Lymphobalstic Leukemia (ALL) patient.

Detailed Description: Acute lymphoblastic leukaemia (ALL) is increasing day by day in less developed countries like Bangladesh. Vincristine is one of the important chemotherapeutic agents used in combination with other medicines to treat Acute Lymphoblastic Leukemia (ALL). Good prognostic outcome of ALL depends on uninterrupted and complete course of chemotherapy. With full course of treatment about 85% of adult patients and 98% of children attain complete recovery. Development of some deleterious adverse effects especially neurotoxicity results in dose reduction, protocol deviation and even abandonment of treatment. About 45% patients develop peripheral neuropathy and more than 33% patients develop autonomic neuropathy who needs dose reduction or treatment protocol deviation. Many studies have been conducted to explore the potential of medicine to prevent or treat neuropathy but still there is no success. This proposed study will be an effort to identify the potential of vitamin B6 (Pyridoxine hydrochloride) and vitamin B12 (Mecobalamin) as preventive measure in reducing the incidence, risk, severity and time of onset of vincristine induced neurotoxicity. This study will be a multicenter, double blind, randomized controlled trial. In this study newly diagnosed ALL patients will be enrolled in induction phase and patients will be randomly allocated into two arms by using online graph pad software. After assessing the baseline characteristics by Eastern Cooperative Oncology Group (ECOG) performance status and Composite Autonomic Symptom Score (COMPASS 31), patient will be provided medicine or placebo. From the day of starting chemotherapy, patients on intervention arm will be administered vitamin B6 and vitamin B12. Vitamin B6 will be given 50 mg thrice daily orally for 5 weeks and Vitamin B12 will be given 500 μg three times weekly intravenously on day 1, 3 and 5 of every week for 5 weeks. On the other hand, patients on placebo arm will be given placebo pill and injection at same interval. Each patient will be evaluated for neurotoxicity on the outset of every 2nd, 3rd, 4th and 5th week by using COMPASS 31 for autonomic neuropathy. Incidence, severity and onset will be compared on both arms. After approval from institutional review board (IRB) every eligible patient will be informed about the intervention and the study. Informed written consent will be taken of the patients who will take part in the study willingly. Patient's anonymity will be maintained and will be used for research purpose only.
